Security Component - Clock Spring
The clock spring is a critical electrical rotary connector used in automotive airbags, installed beneath the car’s steering wheel. It serves as a highly reliable current-transmitting device connecting two components that rotate relative to each other. Primarily composed of a flexible flat cable, a housing designed for rotational movement, wire harnesses (conductive lead wires), and connectors, the clock spring ensures seamless electrical connections for essential components like the driver-side front airbag and horn switch during the left-to-right rotational motion of the steering wheel.
In automotive airbag systems, the clock spring plays a vital role in transmitting electrical signals and completing circuits, enabling the proper functioning of the airbag's Electronic Control Unit (ECU) after a collision.
Safety Component - Gas Generator
The high-pressure gas required for the car's airbag system is generated by a gas generator. When the vehicle collides during driving, the generator’s acceleration sensor detects the peak acceleration signal and the duration of the impact—essentially sensing the magnitude of the collision energy. Based on this collision energy level, the sensor automatically determines whether to deploy the airbag. If the collision energy reaches the predetermined activation threshold, the sensor sends an opening signal, triggering the release of a striker pin. This pin sequentially ignites the primer cap and then sets off the detonator charge within the initiator assembly. The resulting combustion instantly activates the main propellant charge, producing a burst of high-pressure gas. Finally, the gas is expelled through a deflector plate and filtered mesh, inflating the airbag.

New Product Development – Pedestrian Protection
◆ Europe and Japan have already implemented regulations mandating enhanced pedestrian protection.
◆ Current technologies for pedestrian safety include pedestrian airbags and pop-up bonnets. Pedestrian airbags can be installed in the bumper and windshield areas.
◆ The pop-up bonnet design helps prevent occupants' heads from hitting hard components like the engine in the event of a collision.
◆ A pedestrian detection sensor is mounted at the front of the vehicle; if a collision is detected as unavoidable, the system automatically activates the pedestrian protection mechanism.
New Product Development – Low-Risk Deployable Airbag System
◆ Conventional airbags deploy in only one mode and with a single level of inflation energy, which can lead to severe injuries if a child or an occupant sitting too close to the airbag is involved.
◆ Low-risk deployment airbags, however, can "detect" the size and position of the occupant. By precisely controlling the tension in the seatbelt and managing the release of gases through strategically placed vents, these airbags automatically reduce their inflation force when detecting a child or an occupant positioned dangerously close. This prevents the airbag from causing serious harm.
◆ Current technology ensures that both 3-year-old and 6-year-old children remain safe from severe injury when low-risk airbag deployment is activated.
◆ Meanwhile, the U.S. has already implemented regulations to address this issue.
Employing computer simulation as an analytical tool for airbag product design and safety analysis can partially replace automotive crash testing, thereby enhancing efficiency, reducing costs, and shortening the development cycle. The CAE Simulation Team, based on the 3D digital models provided by automakers, uses the occupant injury simulation software MADYMO to build dynamic simulation models of vehicle crash occupant restraint systems. These models include both frontal occupant restraint system analyses and side occupant restraint system analyses. By leveraging the validated simulation models, engineers can optimize airbag designs—specifically targeting types such as the Driver's Airbag (DAB) for frontal deployment and the Passenger Airbag (PAB) for side-impact scenarios.
Engineering Design – Design and R&D
Using CATIA, a software widely adopted by leading automotive manufacturers for product design, ensures seamless integration between Jinheng's product design data and customers' design specifications. This approach not only shortens the product development cycle but also significantly reduces the likelihood of errors during data conversion.
Additionally, employing ANSYS and other structural analysis tools to evaluate the strength and stiffness of components guarantees their reliability right from the initial design stage.
For plastic components, mold flow analysis conducted prior to injection molding provides critical insights that guide both the design and manufacturing of the molds. As a result, this process not only accelerates the mold-making timeline but also enhances the overall quality of the final molds.
